If many are to be believed, a relationship should be a judgment-free zone. So long as everybody is comfortable, it is the one place where you should be able to be your most authentic self, warts and all.
While it is understandable for some to find certain things about their partner irritating or even not good enough, generally speaking, a healthy relationship should involve a decent level of acceptance. Nobody wants to feel like they are constantly being judged by the one they love, especially when they are trying their best to express their love.
